AdBlue® diesel exhaust fluid

"]

Important information about your Audi diesel vehicle

For 2015 Audi A3 Sedan TDI® vehicles and 2016 Audi TDI® vehicles

If the AdBlue® tank runs dry, your vehicle will not restart.

To help ensure proper diesel engine operation, you will need to refill the AdBlue® tank whenever the warning light in the Driver Information Center on the instrument panel comes on. How often the tank runs low on AdBlue® fluid depends on your driving style.

The Driver Information Center warning light will come on multiple times before the tank is empty and the vehicle will not restart.

If the Empty tank! warning appears, your vehicle will continue to run until you turn it off, but will not restart until AdBlue® or a comparable diesel exhaust fluid (DEF) is added.

Complete this vital service via one of two options:

Option A: Have your authorized Audi dealer do it

• If the Driver Information Center warns you AdBlue® fluid is low, you may be entitled to a complimentary refill.[1] See your authorized Audi dealer for details.

Your Owner’s Manual provides step-by-step instructions for refilling the AdBlue® tank.[2] Be sure to follow those instructions carefully. Note: You choose this option at your own expense. You will not be reimbursed by the dealership or by Audi of America.

• Refill the tank: The illustration below shows the location of the AdBlue® fill port. It’s under the blue cap next to the diesel fuel fill port. Add at least two half-gallon bottles to ensure that the system detects the fluid.

• Note these warnings: AdBlue® is a chemical solution that could damage your skin, clothes or vehicle. Use protective gloves and eyewear when handling. Review all package instructions carefully, and, if contact occurs, wash the affected area thoroughly with soap and water. Seek medical attention if irritation persists.

Complimentary AdBlue® refill service applies to the cost of parts and labor at authorized Audi dealerships for all 2016 MY Audi TDI® vehicles and 2015 MY A3 Sedan TDI® vehicles. Owners choosing to refill AdBlue® themselves are not eligible for reimbursement. Complimentary AdBlue® refill service applies for 4 years or 50,000 miles, whichever occurs first, and is transferable to subsequent owners. Complimentary AdBlue® refill service applies only in cases where the instrument panel warning light appears at 1,500 miles before empty or at subsequent mileage warnings, provided the vehicle has not reached its specified maintenance interval. In that case, the AdBlue® refill is a customer expense along with other maintenance, except at the initial 10,000-mile service interval or for customers who have an Audi Care plan. See your Audi dealer for details.

If you choose to forego the complimentary refills at an Audi dealership, you do so at your own expense. You will not be reimbursed by the dealership or by Audi of America.
